Fork of bamtools from https://github.com/pezmaster31/bamtools/. I love the bamtools API and will put mods here that could potentially be part of the general bamtools offering. More extensive mods (such as my desire to create a version that can be dropped into an existing Makefile-driven project) will go in another fork.

Reduced header-associated memory usage

I added the methods

const SamHeader& BamReader::GetConstSamHeader() const { }

to the public interface for BamReader,

const SamHeader& BamReaderPrivate::GetConstSamHeader() const { }

to the public interface for Internal::BamReaderPrivate and

const SamHeader& BamHeader::ToConstSamHeader() const { }

to the Internal::BamHeader class, this is the method that ultimately provides the reference requested by BamReader::GetConstSamHeader().
